Current=2.5A=IInductance=B=5H

We know

$\boxed{\sf Magnetic\:flux=\O=BA}$

$\\ \qquad\quad\sf{:}\dashrightarrow \O=5(2.5)$

$\\ \qquad\quad\sf{:}\dashrightarrow \O=12.5Wb$

At 0.1m, the restoring force would be 25 Newtons. It would probably not be possible to stretch to 5 meters because that would cause a restoring force of 1250 Newtons.
